Friendship disappeared

When I was asking a logical question about vaccination, the nurse chief became sick emotionally as a matter of fact.
It made me sad to know that the friendship that lasted for 30 years would be lost in an instant.
Everyone gets angry when in stuck in the answer.
I will try not to ask questions that hunt people down, but my friendship with her will disappear in the future.
Even if they are friends, they can't do well if they have different backgrounds and different ideas.

Moreover, I think it is natural that conflicts between nations with different systems will occur.
